(Crm1-88) Myinvention relates to delivery mechanism platform stands substantially atthellevel of the for printing' presses, and has Wfor its'object 'the topface ofthe conveyer belt 12. The arrangeprovision of a new and improvedform and arment lfurther is such that, upon delivery of a rangement ofparts by which the folded products signature or other folde'd'productvinto position in the form of complete papers `or pamphlets or upon theplatform, the' platform is adapted to in the form of signatures or otherparts of aV4 descend slightly against the Vaction of thesprings magazineorL book may be stacked evenly in a VS0 alito bring the t0n faee Of SuChfolded Product pile for convenient handling. .Itis another object'substantially to the level of the top face of the of my invention toprovide an'improved arrangedeliverybelt. As a result of thisarrangement,`

l0 'ment by reason of which the pile of vfolded prodinrwhich vtheplatform descends slightly upon'the 65 Y ucts may beWithdrawnfreadilyand'quickly from delivery of each addtOnal palier intoDOSitiOn position so as to permit a newf pile to be stacked. thereon forkeeping the upper surface of the pile It is another object ofmyinvention to improve 0fA papers at all times in Substantial alignmentdevices of this type in sundry details hereinafter with the face of thedelivery belt, but at a slightly pointed out. The preferred. means bywhichI lower level than that of the top face of the belt, 70v haveaccomplished my several objects are illus- Successive papers aredelivered smoothly and trate'd in the drawingV and are hereinafterevenly t0 the pile. `In the arrangement ShOWn in specifically described.That which I believe to Fig. 2, a signature is shown in position upon benew and desire to cover by Letters Patent is the platform 17, With -aplurality 0f additional 20 set forth in the claims.

Collars 19are pro- Upon the link 33 I have mounted a coil spring vvidedv on theupper ends of the rods 16 'serving V34, one end of which bears against acollar g to limit the upward'movementwof the platform.` 35 carriedby thelink 33 and the vother vend of The-arrangement is such that when theplatfor'iri which i bears against a bracket 36 Y rising from 17 is notprovided with a load the'top face of the the base 10. The arrangement issuch that the 110 spring r34 normally holds the arm 30 in the positionas shown in solid lines in Fig. 2, in which position the arm serves tostop the outward movement of successively delivered signatures. Whenupon the continued operation of the press and the delivery belt 12 apile of signatures or other folded products have accumulated upon theplatform 17 in neatly piled superposed po-V sition thereon, an operatoris able to grasp such pile by the outer corners thereof and withdraw thesame very readily and quickly toward the left in said Figs. 1 and 2.,the arm 30 being adapted to yield readily vagainst the 'action of thespring 34 into the position as shown in dotted lines in Fig. 2 forpermittingsuch, removal of the papers. The springs 18 thereupon bringthe platform 17 again to its elevated position ready to receive the nextsuccessive signature from the delivery belt. At the same time the spring34 serves to vbring the arm 30 again toA normal position as shown insolid lines. o

" For providing additional assurance thatI the papers will be kept inevenly piledk arrangement on the platform, I have provided means yforjostling 'the' papers slightly as they are deliv-l ered. In theconstruction illustrated, this jostling effect is brought about throughthe medium ofjthe arm l which is given a limited swinging movementtoward and from the platform. The 30 "ward the `platform 17 when it isreleased after spring 34 serves to provide .the movement toa movementaway from the platform. The means for effecting movement of thearm awayfrom` the Iplatform against the action of the spring .34'comprises ayoke lever 37 mounted upon a "rock shaft 38. The shaft `38 is actuatedby means of a lever 39 mounted on said shaft, with'its free endconnected to an upwardly extending link 40. The upper end of the link 40is en- ,gaged during a portion of the rotation of the "sprocket gear 1 5by a pin`41 extending outwardly from said gear; such pin 4l servingtotforce the link 40 downwardly. This movement of the link serves torock the shaft 38, causing the .,lever 37 to swing toward the right inFig.2,

'serving by engagement with a pin 42 carried by the link 33 to move thelink v33 `toward the right in said figure so as to swing the arm 30toward'the left. When the pin 41 inthe rotation of the gear 15 reachesthe lower part of its 'movementit passes out of engagement with theupper end of thetlink 40, whereupon the spring 34 is free to lmove thearm 30 again toward the right into engagement with the face of the pile`of signatures upon the platform 17 so as to deliver a light blow uponany V paper extending Yslightly beyond the face of the pile. Thisintermittent jostling movement of the arm 30 serves to keep etheedges ofthe signatures in evened --position with respect to each other. AWhile Iprefer to employ the construction substantially as shown in the drawingand as above described, it is to be understood that my invention is notlimited thereto except so far as the claims may be so limited by theprior art, it being vunderstood that' changes may well 'be made in theconstruction without departing from my invention.
